2,7-Bis(2-(dimethylamino)ethoxy)-9H-fluoren-9-one dihydrochloride CAS 28712-30-3

Description

Compared with other compounds in its class, the molecular weight of 390.91 g/mol gives 2,7-Bis(2-(dimethylamino)ethoxy)-9H-fluoren-9-one dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,7-Bis(2-(dimethylamino)ethoxy)-9H-fluoren-9-one dihydrochloride (CAS 28712-30-3), molecular formula C21H26N2O3HCl and molecular weight 390.91 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2,7-Bis(2-(dimethylamino)ethoxy)-9H-fluoren-9-one dihydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
